COMBINED CAR AND AIR BRAKE COUPLING.

SPECIFICATION forming part of Letters Patent No. 501,624, dated July 18, 1893.

Application filed March 3l, 1893. Serial No. 468,456. (No model.)

To a/ZZ whom t may concern/.-

Be it known that I, PHINEAs PELTON, a citizen of the United States, residing at Persia,

' in the county of Harrison and State of Iowa,

have invented a new and useful Combined Automatic Oar-Coupling and Automatic Air- Brake, of which the following is a specification.

My invention relates to that class of carcoupling heads including means for automatically effecting a coupling of the brake, heating, or signal-pipes, though in the present instance it is intended more particularly for coupling the brake-pipes.

The objects of my invention are to produce a cheap and simple construction of automatic coupler including in its make-up means for effecting an automatic coupling of the brakepipes of two cars; to so construct the coupler that the same may be readily uncoupled and set for coupling at the sides of the car and without the necessity of stepping thereinbetween; and furthermore, to adapt the coupler to engage with the ordinary link-and-pin coupler commonly used.

With these and other objects in view the invention consists in certain features of construction hereinafter specied and particu'- larly pointed out in the claims.

Referring to the drawingsz-Figure 1 is a perspective view of the front end of a car, the

same having av coupling-head.constructed in accordance with my invention. vFig 2 is a vertical longitudinal sectional view. Fig. 3

is a horizontal sectional view. Fig. 4 is a detail in perspective of the head, the same being adapted for link-and-pin connection. Fig. 5 is a detail of the link attachment employed for this purpose.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 designates the timbers of a car-frame, and the same are provided upon their under sides with convenient bearings 2 in -which there is journaled for rotation a transverse shaft 3 whose ends project beyond the bearings and are provided with suitable hand-wheels 4, or it may be with levers as desired. To one of those timbers 5 in which the draw-bar 6 of the coupler hereinafter described is located there is secured a bearing standard 7, and the same is provided just below the shaft 3 with an opening 8. A boss 9 upon the shaft at one side of this standard is provided with a lug 10 formed on its inner face, and when the shaft is rotatedvso as to bring the lug opposite the opening, said shaft is p by means hereinafter specified, slid in its bearings so that said lug takes into and interlocks with the opening, whereby the shaft is prevented from again rotating until the shaft has been slid in a retrograde direction so as to disengage the front end with an inclined face as shown. The

hook is provided at its outer side with an eye 17, and to this is connected one end of a chain 18, the remaining end engaging with an eye 19 with which the shaft 3 is provided. Each of the openings 12 and 13 is provided with vertically opposite pin-holes 2O and 21, respectively, and located therein are pins 22 and 23, respectively.

24 designates a coupling-head or jaw, and

the same is provided at its rear end with a reduced tenon 25, which is adapted to tit removably in the chamber 13 and to be secured in position by means of the pin 23 which passes through the opening 21 and through a corresponding opening formed in the aforesaid tenon. The outer end of the couplinghead or jaw is rounded, and at its outer side is provided with a vertical shoulder 26. The inner face of the head or jaw 24 is provided with a vertical recess 27, and said recess has formed in its bottom a recess 28. A slide 29 is mounted in the latter recess and is provided at its rear side with an outwardly projecting arm or lug 30 which extends from the face of thecoupler toward the draw-hook. A spring-arm 31 is secured to the under side of the jaw and is provided'with a coil at the inner corner thereof, and has its upper branch.

32 depressed against the rear side of the lug cut-oit 29 is normally forced forward into the recess 28. A passage 33 extends from the bottom of the head or jaw 24 upwardly to a point opposite the recess 28 when it takes a horizontal direction and communicates with the recess, so that the slide or cut-oi when,l

nototherwise influenced than by the spring covers said passage. A face-plate 34 is located in the recess 27 and snugly tits the same, said,

face-plate having its outer surface made smooth by grinding or otherwise and provided opposite the recess 28 and the passage 33 with,

a slot or opening 35.

One member 3G of a hand-coupleris inserted upwardly into the lower end of the passage' 33 `and adapted to be removably connected therewith is the remaining member 37 of said coupler, which, as usual,is attached to,\in this instance, the brake-pipe 38.

Two coupling-heads constructed after the manner above described coming into engagement it will be seen that the hook of one head will engage with thevertical rib 2G of the other, and the two face-plates 34 coming.

against each other their slots 35 will register, forming a tightjoint, and the ends ofthe'jaws will abut against the lugs 30 of the sliding cut-offs forcing the same backward `against the tension of their springs and thus opening` up communication between the air-pipes ot` Coiled springs 39 are located in rear of the pins 15 of the draw-1, hooksso that the locking of the coupling-headsl aswell as the coupling of `the brake-pipes becomes automatic. By rotating the shaft 31 theg hooks are withdrawn fromengagement withg' the coupling-heads against the tension of their springs and may be locked in thisset positicn ready to recouple by the means heretofore de-z scribed. Itwill be seen that as soon as thef Acoupling-jaws `or heads become disconnected the cut-offs are au tomaticallyoperated to close the two coupling-heads.

the brake-pipes.

In operation an attendant stands at'the side of the car and grasps the hand-wheels of the two cars, one in each hand, rotating them to uncouple.

Iwill now proceed to describe the attachment and means for securing the same in postion,'whereby the head will be adapted to couple with the ordinary form of link-and-pin coupler, which, as is well known, is sometimes necessary. It is in this connection that the recess 12 is utilized, and a recess 42 is also provided in the front face or end of the coup ling-head 24, the saine being provided further with a vertical pin-opening 43 in which a pin 44 is mounted.

45 designates a link adapted to enter an ordinary link-andpin draw-head, and the same is provided at its rear side with ashort'tenon or terminal 46 having an vopening l47 and `adapted to fit the recess 42 and be connected therewith by the pin 44, and a long terminal 43whose rear end is adapted to tit within the recess 12 and is provided with a pin-hole 49 adapted to receive the pin 22. Stop-shoulders 50 are located upon the long and short tern1inals, whereby the link is steadied. When not in use the link may be conveniently suspended upon a T-shaped stud 51 projecting from the side of the coupling-head.

Fromthe foregoing description in connection with the accompanying drawings it will be seen that I have provided a cheap and simple construction of vcombined car and airbrake pipe-couplin g, the coupling operation of both car and air-brake being automatic; and furthermore, that a vdisconnection may bc readily etected without stepping between the cars for thispurpose.

Various changes in the details of my invention may be madewithout departing from the scope thereof, and I therefore do not limit the invention to the particular details heretofore described,'but lhold thatI may vary the samefto any extent within the knowledge of the skilled mechanic.

Having described my invention, what I claim is 1. In a vcar-coupler, the'combination with a draw-head providedupon its front face and at' one side of its center with a forwardly-projectin g cou'plinghead whose outerside is provided with a vertical shoulder, of a hook piv oted at the opposite side of the draw-head and extending in front of the same oppositelthe Vcoupling-head, a spring for normally pressing the hook inward at vits outer end, bearings, one of which is a `standard having `a recess, a reciprocating shaft mounted in the bearings, wheels for operating the shaft,lconnections `between the hook andthe shaft, and a boss mounted onthe shaftand provided with a lug for engaging thefrecess` of the standard, substantially as specified.
